Thanks for checking, @Jeff_Zhang ! Just want to clarify regarding refreshing the state: you will need to toggle off & save, then toggle on again & save. Otherwise, format assistance/entity matching won't refresh. You will see a spinning wheel in the UI when it's refreshing.
Additionally, do you see values such as GATE-OUT, GATE-IN, etc., in the format assistance?
Last resort: try recreating the Genie space and see if it works. You can clone a Genie space; this will recreate the space: https://docs.databricks.com/aws/en/genie/set-up#clone-a-genie-space
